SAMUEL HENDERSON, NEKOMA, ILLINOIS.

STOVE-GRATIS.

To all whom it may concern:

Be it known that I, SAMUEL HENDERSON, a citizen of the United States, residing at Nekoma, in the county of Henry and State of Illinois, have invented certain new and useful Improvements in Stove-Grates; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to grates for cook stoves and other similar stoves or heaters; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed, whereby the height of the grate in the fuel chamber of the stove is adjusted, and whereby the grate may be tilted to dump ashes and cinders.

In the drawings, Figure 1 is a front view of a grate constructed according to this invention, showing portions of the stove in section. Fig. 2 is a cross-section through the grate, taken on the line m--m in Fig. 1, and showing the position of the parts when the grate is fully raised in dotted lines. Fig. 3 is an end view showing the operating mechanism.

The grate 2 is of any approved pattern, and is rectangular in shape, so that it will slide freely in the fire-box or fuel chamber 3 of the stove. Parallel shafts 4: and 5 are journaled in the ends of the fuel chamber under the grate, and are operatively connected together by means of two toothed segments or pinions 6 and 7 secured on the respective shafts and gearing into each other. ()no segment 6 is slidable on a rectangular portion 8 of the shaft 4, so that it can be slid out of gear with the other segment. A handle 9 is provided for oscillating the shafts, and it is preferably secured to the slidable segment 6.

A pawl 10 is pivoted to the fuel chamber by a pin 12, and engages with the teeth of one of the segments, and operates to sustain the grate in any desired position, The pawl preferably engages with the teeth of the non-slidable segment.

The shaft 4 has a pair of arms 1 1 secured on it, and the shaft 5 has a pair of arms 15 Specification of Letters Patent.

secured on it. These arms project downwardly when the grate is in its lowest position, as shown by full lines in Fig. 2. The arms 14 are connected to the grate by links 16 and pins 17 and the arms 15 are connected to the grate by links 18 and pins 19. The links 16 are arranged on the opposite side of the two shafts from the links 18, and the grate has perforated lugs 20 on its underside for receiving the upper pivot pins of th arms.

When the handle is moved in the direction of the arrow in Fig. 3, the grate is raised to the position shown by dotted lines in Fig. 2, and is sustained by the pawl at that height or at any desired ii'itermediate position in thefuel ehai'nber. In this manner a deep fire or a shallow fire can be arranged for at will, and to suit the requirements as they vary from time to time.

\Vhen the fuel is to be dumped one segment is slid out of gear with the other segment, and the handle is moved in the direction of the arrow. This raises one side only of the grate by means of the arms and links pertaining to that side, and the ashes and cinders slide off the grate into the ash-pit below it.

\Vhat I claim is:

The combination, with a fuel chamber, and two parallel shafts journaled therein; of a grate slidable in the chamber and arranged above the said shafts, arms secured on the said shafts, links pivotally connecting the arms with the grate, toothed segments or pinions mounted to revolve with the said shafts and gearing into each other, one of the said toothed segments or pinions l'ieiug slidable longitudinally on its shaft into and out of gear with the other toothed segment or pinion, and an operating handle secured to the slidable segment or pinion and affording a means for dumping the grate by raising one side portion of it.

In testimony whereof I have affixed my signature in the presence of two witnesses.

SAMUEL HENDERSON.
